ABSTRACT
In this paper CdO thin film has been prepared by sol-gel dip-coating method on glass substrate. The film was characterized by X-Ray diffraction, UV-Visible spectroscopy and photoluminescence spectroscopy for structural and optical properties of CdO thin film. The XRD pattern shows that film is polycrystalline in nature and has a cubical structure with orientation along (111) plane. The diffuse reflectance spectra for the film is studied in wavelength range 400-800 nm. The direct energy band gap of 2.50 eV is found for the film using modified Kubelka-Munk function. Photoluminescence spectra shows one sharp peak at 540 nm due to oxygen vacancy of cadmium oxide.
